Based on the provided legal document, the court's decision emphasizes the importance of strictly adhering to procedural rules regarding discovery applications. The key points are as follows:

1. Discovery against non-parties must be pursued under the specific procedural mechanism outlined for such cases, namely O 24 r 7A of the Rules of Court 2012. Using the provisions applicable only to parties (O 24 rr 3 and 7) for non-party discovery is procedurally improper and legally unsustainable (!) (!) .

2. The essential elements for a valid discovery order include that the documents must be in the possession, custody, or power of the party from whom discovery is sought, and that the documents are relevant to the issues in dispute. Mere relevance or association with the documents is insufficient without establishing legal control or possession (!) (!) (!) .

3. Discovery should not be used as a fishing expedition. Applications must be specific, justified, and demonstrate a genuine need for particular documents. Broad, indiscriminate requests lacking specificity are considered impermissible and indicative of an attempt to engage in a fishing expedition (!) (!) (!) .

4. The court will scrutinize whether the documents sought are within the control of the party and whether there is a clear link between the documents and the issues in dispute. Failure to establish this control or relevance renders the discovery application defective (!) (!) (!) .

5. The court highlighted that the mere assertion of relevance without detailed explanation or evidence is insufficient. The applicant must substantiate the relevance and necessity of the documents at the time of filing, not afterwards (!) (!) .

6. When documents are held by third parties, the proper procedural route involves specific mechanisms to obtain discovery, and the applicant must demonstrate legal control or enforceable rights over those documents. Without such proof, discovery against third parties is improper (!) (!) (!) .

7. The application in the case was flawed because it sought broad, non-specific documents from multiple entities, including non-parties, without establishing their relevance, possession, or control. This approach was deemed a fishing expedition and was therefore dismissed (!) (!) (!) (!) .

In conclusion, the court reaffirmed that discovery applications must be carefully grounded in legal principles, with clear relevance, control, and justification, and must avoid broad or speculative requests that amount to fishing expeditions.
